Renew IP address does not

We are invited by cable network access configuration. We can users invited to logon successfully, but he never does the IP address assigned reviews vlan.

  1. Click Administration, and then click comments.
  2. Click settings.
  3. Expand comments, and then expand Configuration multi-portail.

VLAN DHCP IP Release/renew

This affects the CWA user login flow when network during the final authorization access switches the guest VLAN on a new VLAN. In this case, the old client IP must be released before you change the VLAN and a new IP of comments must be requested through DHCP once the new access VLAN is in place. Operation to renew the redirections of the Cisco ISE Server release browser to download an applet to perform the INVESTIGATION period.

Exit time delay must be low because it must take place immediately after the applet is downloaded and before the ISE Cisco server redirects the n to be re - authenticate with a request for costs. The default value is 1 second.

The delay of the COA delays the ISE Cisco of the execution of the COA. Here, it should be enough time to allow the applet to download and run the IP version on the client. The default value is 8 seconds.

The delay to renew the value is added to the output IP value and does not start the clock until the control is downloaded. The renewal he need enough time so that the certificate of authenticity is allowed in the process and the new access VLAN granted. The default value is 12 seconds.
